DDN E MAIL MSG, MILNET NETWORK CHANGE DIRECTIVE MS1-0158, 14 AUG 91 B. DISA/SERVICE/AGENCY MEETING, INTERNET ROUTER SERVICE SUBSCRIBER REQUIREMENTS, 7 MAY 91 C. DISA(DCA) MSG, MILNET GATEWAY AND HOST REHOMING ASSIGNMENTS, 131811Z JUL 90 D. DISA(DCA) MSG, DEFENSE DATA NETWORK MAILBRIDGES/CORE GATEWAYS, 281648Z DEC 90 1. This message provides guidance and status information concerning the Defense Data Network (DDN) Mailbridge (MB) and the two functions which it fulfills: (1) Internet Routing Service (IRS) using Exterior Gateway Protocol (EGP) and (2) DDN connectivity to the non MILNET Internet, commonly referred to as the NSFNET. Request widest dissemination. The following topics will be addressed: -- EGP Update Options (see also Para 8, below, for detailed assignments). -- Randolph Mailbridge Network Address Change Effective 9 Sep 91. -- Non-compliance with Internet Control Message Protocol (ICMP) Re-Direct Messages. -- Planned Relocations for Mailbridges. -- Planned NSFNET (Internet) Connection Changes. -- Replacement System for MB/EGP Servers. -- Detailed EGP Server Assignments. 2. EGP Update Options. MB software Patch 11, fully deployed as of 30 Jul 91, provides the capability to restrict the EGP update size by eliminating announcement of networks and gateways served by the NSFNET and provides a default routing assignment (zero default route) to reach those non-advertized networks. Due to the update size exceeding 8K bytes and after consultation with relevant gateway administrators and managers, the limited update was activated at BMILBBN, BMILISI, BMILDCEC, and BMILOAK. Full MILNET/NSFNET network update announcements continue to be provided by BMILRAN, BMILAMES, and BMILMITRE at this time. See Ref A for details. See Para 8, below, for specific assignments. 3. Randolph MB Network Address Change Effective 9 Sep 91. As a result of the planned deactivation and removal of PSN 101 at Randolph AFB TX on 9 Sep 91, it is necessary to re-home the MB to node 51. The new network address is 26.1.0.51. All gateways acquiring EGP updates from the MB at Randolph should change their software accordingly. Use of BMILAMES (26.20.0.16) or BMILMITRE (26.20.0.17) as a secondary source for full EGP updates, pending required changes, may be used as an interim alternative. However, strict compliance with the assignments detailed in Para 8, below, is critical to overall operational effectiveness of the EGP service. 4. Non Compliance with ICMP Re-Direct Messages. When the MB is used as a default route to other addresses, the MB searches its tables to see if a direct route is available. If so, the MB sends a protocol message to the originating address of that packet advising of the direct address. It is expected that properly implemented Internet protocol software will respond to that re- direct command for all subsequent packets destined for that address. Many hosts/gateways are not responding to the re-direct commands, which results in extraneous packets (i.e., packet plus re-direct message plus retransmission for every packet) traversing the network and poorer response to the user. This mis-use also adds additional processing requirements to an already stressed MB. In the future, chronic failure to respond to re-direct commands will be brought to the attention of the parent service/agency for corrective action. Continued non-compliance may result in denial of re-direct service to the offending host/gateway with resultant lost traffic. 5. Planned MB Relocations. As a result of MILNET re-designs driven by changing requirements and funding cutbacks, the packet switching nodes currently connecting BMILAMES (26.20.0.16), BMILISI (26.6.0.103), and BMILMITRE (26.20.0.17) Mailbridges will be deactivated and the Mailbridges re-homed. As soon as a firm re-home location and schedule is determined, an announcement of the new addresses will be provided. 6. Planned Changes to the MILNET/NSFNET Connections. In an effort to provide more efficient and economical service to those subscribers exchanging traffic between the MILNET and the NSFNET, or non-DoD Internet, it is planned to provide this interconnectivity via Internet protocol routers to be located at Ft Detrick (for the fix-east connection) and at Oakland (Navy) CA (for the fix-west connection). MILNET entry points for this Internet traffic will be at one of eight IP router locations. This change will off load this store and forward function from BMILMITRE and BMILAMES Mailbridges and provide a more efficient and economical exchange of MILNET/NSFNET traffic. Further information and specific address assignments will be provided as this plan matures. In the interim, Internet traffic should be routed as specified in Ref C and DDN Management Bulletin 74. 7. Replacement System for MB/EGP Servers. As announced at Ref B, a replacement system for Internet routing service is required because of current Mailbridge hardware and software limitations in addition to Exterior Gateway Protocol (EGP) limitations. A detailed plan describing this replacement system, along with a schedule of events, is being forwarded under separate cover to principal offices of the Deparment of Defense Services and Agencies for review, comment, and concurrence. The plan includes a migration from EGP to Border Gateway Protocol (BGP) and replacement of the current Mailbridge hardware and software within the next two years. EGP will be supported, at least to some degree, until all gateways can convert to BGP. Status updates and required modifications to subscriber gateways will be published as needed. 8. Detailed EGP Server Assignments. a. Strict compliance with the assignments enumerated below is essential to providing adequate service to all users. Failure to comply with these assignments could result in the denial of Internet routing service updates and/or exchange of traffic with the non DoD Internet. Refs C and D previously requested assistance in this matter. b. These EGP Server assignments supersede those provided by Ref C and DDN Management Bulletin 74. c. Air Force concentrators will continue to use either BMILDCEC or BMILOAK as their EGP servers. d. Internet traffic assignments will remain as assigned by Ref C and DDN Management Bulletin 74 (see Para 6, above). e. Host/Gateway Administrators should initiate compliance with this message as soon as possible with complete compliance prior to 30 Sep 91. f. Questions or issues should be directed to the DDN Monitoring Center Trouble Desks: (1) CONUS: 1-800-451-7413 or (703) 486-1982 or (DSN) 231-1787. (2) Europe: (ETS) 430-5532 or (MIL) 2729-5532 or (DSN) 314-430-5532 or (CIV) 011-49-680-5532 (3) Pacific: (808) 656-1472 or (DSN) 315-456-1472 g.

Specific EGP assignments. Each gateway should acquire as EGP peers (neighbors) only those two EGP servers assigned. Failure to comply may result in erroneous/conflicting updates or loss of capability to exchange traffic with both MILNET and non DoD Internet gateways.
